I have been wrestling with myself over the pro's and con's of these filters, and I was wondering what this group thinks. I currently own Lumicon's OIII and UHC...
Hi Mark, I've been using one for years and can highly recommend it. The majority of comets show little to no enhancement but on certain ones, the filter works...

... Michael, Exellent images, especially 73P-B20060601UT340s3x100s%20Kopie.JPG where there seems to be the suggestion of material most of the way between your...
Hello Michael, Nice images indeed, and I think it's neccessary to confirm those faint comets, as they seems to be unknown ones. Unfortunately the weather at...
Hello Michael, I just take a look -- sorry, as your FOV is large, these fragments might be fragment G (? I thought it had disappeared) or something else. ...
Hi Mark, I am a visual comet-hunter, with a deep interest in the imaging you guys do. I have used a Swan band filter for years, and it definitely improves the...
Hello Quanzhi and Peter thank you for given hint. i don' believe, that this are G-fragments. i send to IAU some positions. maybe i will hear something. michael...
To the observers, Here is a movie of comet C/2004 B1 Linear on June 6.(last night) The movie shows the movement in 82 minutes time.Moonlight was strong during...
To the observers, These are observations of comet C/2004 B1 (Linear) on June 8. The image is a composite of the data of all images of the session. The movie...
Ralf, (and all), ... please post such "routine" observations with no special events rather to Comet- Images instead of comets-ml. Please remember my polite...
Interesting orbit for northern parts. Any one think this will do better than 13th mag? I wouldn't know what to look for which would signal a good better show...
Hi Mike, according to GUIDE 8.0 software (after loading the elements in), this is the ephemerides at 5 day intervals. Better for you northern folk - not for us...

Hi all, For who is interested; I have posted a movie in the comet-images group, all data is combinated of 2 nights observations.Total stretch of the movement...
Anyone have a good estimate of total seperation of 73P fragments now? I'd like to get an estimate of the "cloud" size radius if possible. And are small...
Hi all, few hours ago, IAUC Nr.8721 reported the discovery of yet another comet by R. H. McNaught. Currently this target is placed in Centaurus, some 37...
I saw no evidence visually, or in the instrumental magnitudes to believe there is any variation in the brightness of C/2006 L2. The central condensation is...
